You’re not very good at maths are you lol. Half of $310mill is $155mill. Add on a bit more as this stand will have more corporates, likely a change room for each of the three tenants, plat members section etc so let’s say $175-200mill for the west stand. Fill in seat sections and a roof for south stand $30mill. New north stand $40-50mill. Add on led lighting, new entrance ways, permenant food outlets in the north end grass area etc and other add ons around the ground. You’re at the $300mill+ mark. They’ve costed it , it allegedly came out around the $350mill mark. The great news is of it happens Perth will have a great nrl stadium for its new club.
